Title: Ultrasonic cosmetic device
Inventor: NISHIMURA SHINJI
IPC: A61H23/02
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To suppress unnecessary temp. elevation at a part where a probe is brought into contact with the skin. SOLUTION: A detecting circuit 5 detects contact and non-contact or a metal part 1 to the skin by utilizing that electric impedance of an ultrasonic oscillator 2 changes by contact and non-contact of the metal part 1 to the skin and converting the electric current Ic passing through the ultrasonic oscillator 2 to an electric voltage Vd and comparing it with a reference electric voltage Vref by means of a comparator CP. When contact is detected by the detecting circuit 5, a constant-voltage circuit 8 makes the level of constant voltage outputted to an ultrasonic oscillating circuit 4 to a standard voltage Va1 and when non-contact is detected, it is switched to a constant voltage Va2 being lower than that.  When non-contact of the metal part 1 to the skin is detected by the detecting circuit 5 like this, unnecessary temp. elevation of the metal part 1 can be suppressed by lowering the level of untrasonic wave emitted from the ultrasonic oscillator 2 through the metal part 1 by means of an oscillation control part 6.

Title: Driving method of ink-jet print head
Inventor: KOBAYASHI ATSUSHI
IPC: B41J2/055
Filed: 1992-08-25
Abstract: PURPOSE:To shorten the restoration time of an ink meniscus to obtain a quick response by a method wherein when the driving voltage is changed to increase the volume of a pressure chamber, the change ratio of the driving voltage to time is set at a small one at the start-up time of voltage application and increased to a larger one at the succeeding time. CONSTITUTION:In the wait state, a piezoelectric element 4 is in discharged state and charge voltage is applied to it while the change race is increased with time. As the volume of an ink chamber 1 is gradually increased at the beginning step of voltage application, an ink meniscus 6 formed at the tip of a nozzle 2 is recessed a little and then begins to restore due to the surface tension. However, the meniscus 6 stays at a position recessed a little from the tip of the nozzle because the applied voltage is gradually increased, resulting in a rise in the volume increase rate of the ink chamber 1. After the applied voltage reaches a specified charge voltage, the voltage is kept unchanged to stabilize the position of the ink meniscus 6, and then a sharp discharge takes place to reduce the volume of the ink chamber 1 and spout ink 5 through the nozzle 2.

IPC: F25D17/02
Filed: 1988-09-10
Abstract: PURPOSE:To suppress a decrease in the temperature of brine to a freezing point intrinsic for the brine even in a cold district or in winter and to prevent devices from damaging due to freezing by operating brine temperature detecting means to operate predetermined freezing preventing means. CONSTITUTION:When an interior temperature in a refrigerator is cooled to the first set temperature TB of a brine freezing temperature detecting thermostat Th3, a relay X2 is energized by closing a contact Th3-c to close a normal- open contact X2-a cooperating therewith and to open a normal-close contact X2-b. In this case, since the contact Th1-b of a defrosting thermostat Th1 is closed, heaters H1, H2 are energized to heat brine circulating in a cooler 7, and brine stored in a tank 6 is mixed with the heated and returned brine to start rising at its temperature. When the temperature in the refrigerator arrives at the upper limit set temperature TC of the thermostat Th3, the contact Th3-c is opened to deenergize the relay X2. Thus, the heaters H1, H2 are deenergized to stop heating of the cooler 7.

Filed: 1985-10-11
Abstract: PURPOSE:To suppress an overcurrent in case of switching parallel and series of a plurality of main motors by providing a current limiting reactor in a crossover circuit. CONSTITUTION:When starting an electric railcar, cam switches 11, 12 and an S switch 5 are closed. As the rotating speed of a main motor increases, the resistances of variable resistors 3, 4 are sequentially reduced, and when the resistance values become zero, cam switches 21, 22 are closed to a series circuit. Then, the resistance values of variable resistors 3, 4 are raised to the maximum, and the switches 11, 12 are opened, and a P switch 6 and a G switch 7 are simultaneously closed. Thereafter, the switch 5 is opened to switch to a parallel circuit. An overcurrent tends to flow until the switch 5 is opened, but a current limiting reactor 8 suppresses it.

Title: Infrared co detector
Inventor: SAKAI JIRO
IPC: G01N21/61
Filed: 1996-08-10
Abstract: PROBLEM TO BE SOLVED: To stabilize CO gas concentration for a long period by providing a CO gas sealing pipe made of aluminum. SOLUTION: CO gas is introduced from a CO gas cylinder into an equipment body 10 under vacuum, and when the gas reaches a prescribed concentration, an aluminum-made pipe 8 is caulked by use of a caulking tool 16. Thus, CO gas of the prescribed concentration can be sealed within the equipment body 1-0. Since a gas seal part 9 is formed of chemically stable aluminum, the CO detector is never influenced by the ambient temperature even when used in integration into an infrared analyzer, and the CO gas sealed within the equipment body 10 is never chemically reacted with the aluminum-made gas seal part 9. Therefore, the concentration of the sealed CO gas can be stabilized for a long period.
